2.9 SOURCE QUALITY CONTROL

.1 Non-Conforming Work: Pre-finished post-formed metal panel assemblies may exhibit certain behaviors common to all fabricators. Oil canning is a moderate deformation of sheet metal surfaces, typically caused by uneven stresses at fastening points. Metal forming during panel fabrication may result fine cracks in finishes (crazing) at outer edges or bends. Take reasonable steps to prevent and mitigate these effects. Mild "oil canning" or “crazing” are not deficiencies.

Part 3 Execution

3.1 EXAMINATION
